This invention relates broadly to new and useful improvements in building structures having simulated log walls and more particularly to a novel method of forming metal lath so that the latter automatically assumes a shape simulating the logs when nailed or otherwise fastenedv to a wall of the building, to a novel brake for forming the metal laths, and to the formed sheet of metal lath obtained by practice of the method or operation of the brake.

This is a division of mycopending application Serial No. 694,861, which was flied on the ilith day of September, 1946.

An important object oi the invention is to provide a novel method of forming metal laths so that the latter' automatically assumes a desired shape or coniiguration when attached to the Wall of a building.

Another object of the'invention is to provide a novel method of forming a simulated log wall.

Another object of the invention is to provide a novel brake which permits the method to be practiced eiilciently and quickly.

Still another object of the invention is to pro' vide a brake of the above-mentioned character that is simple in construction and eilicient in operation.

Yet another object oi the invention is to provide a novel preformed metal lath'that can be applied easily and quickly to the wall'of a building and which naturally assumes a desired shape or conguration when attached to the wall. v

Other objects and advantages of the invention will be apparent during the course ofthe following description.

This invention relates to the same subject matter as my prior United States Patent 2,045,482, dated June 23, 1936. According to the patented invention, a simulated log wall is obtained by nailing or otherwise fastening formed sheet-metal laths 20 to the vertical wall of a building and then covering the laths with concrete or plaster 22. A construction of this type is illustrated in Fig. 1 wherein the building wall is shown as comprising siding 24 which is nailed to studs 26 and covered with a layer of tar paper '28 or the like. The laths 20 are formed with relatively wide arched portions 30 and the latter are separated by webs 32 which are nailed to the siding 24 and hold the arched portions spaced from and rigidly iiXed with relation to the wall.

Webs 32 may he formed integrally with the arched portions 3l! on both sides thereof, as in the case of the middle web in Fig. 1, or they may merely comprise overlapping marginal iianges on adjacent sheets of metal laths, as in the case of the two endmost webs. Any desired number of arches 3'0 can be formed in a single sheet of metal lath, and, if more than one sheet is required, the marginal flanges of adjacent sheets are overlapped and nailed to the wall as shown in the drawings. Metal lath is made in stock sizes, and I have found it convenient, in the present invention, to use sheets which are approximately `four feet square. Manifestly, however, this is merely a matter of convenience and adaptability, and any suitable size sheet can be used, depending upon the exigencies oi the particular situation. When properly formed and aflixed to the wall, the lath forms a relatively rigidmatrix for the concrete or plaster 22; and, if the latter is properly colored and artistically formed, an effect is produced which closely resembles or simulates an actual log structure. The simulated log structure is reproof and has the advantage of vproviding 3 heat-insulating air spaces between the wall of the building and the metal laths 2i).

As suggested, the present invention is concerned with a method of and means for easily and quickly preforming a metal lath so that it automatically assumes the shape shown in Fig. l. when applied to a wall. According to the present invention the lath is formed in a brake which comprises a medial beam 34, leaves 35 at oppo-M site sides of the beam, panels 33 along the outer edges of the leaves, and a removable leaf iii which is adapted to be mounted separately on both leaves 36 as shown in Figs. 4 and 7. The entire4 idly between it and the removable leaf it. This operation forms a second relatively wide section orside 54 irr the-lath '20 and simultaneously forms structure conveniently can be placed on a suitable supporting platform e2. While the brake may be arranged to operate by hinging the various;y

parts thereof to swing either downwardly or upwardly relative to one another in a bending operation, the latter construction is preferred and is here shown because it is simpler than the other. Leaves 3Q are fastened to the beam sil by hinges M, and the panels 36 are fastened to leaves by hinges llt. In this connection it will be observed that' all of the hinges are set into or ernbedded in the top surfaces of the partsso that these surfacesl are contiguous to each other. Furthermore,- th'e hinges are arranged so that all of the articulated parts fold upwardly. 5-8 show the manner in which panels 3d swing upward-ly at right angles to their respective leaves 3E, and Figs. 6 and '7 show the manner in which the leaves swing upwardly substantially at right angles to the beam 34. Preferably handles fl? are provided at the outer` edges of panels 33 (Fig. l) to facilitate manual actuation of the parts.

It will be observed that the beam 35 and panels Stare relatively narrow, while the leaves 35 and fidare relatively wide; moreover, the leaves and it preferably are similar in size and shape,` so that the removable leaf it coincides with the leaf 36 on which it is mounted.

While removable leaf sil may be held inA position by hand during operation of the brake, it is preferable, particularly in larger brake sizes, to provide some means for locating and holding it relative to the leaves 35. One way in which this can be accomplished conveniently is to provide one ofthe leaves with pilot pins which enter and snugly fit locating holes in the other leaf or leaves. In the form of the invention here shown by way of illustration, the removable leaf lll carries pilot pi-n's d8 adjacent each end thereof, which pinsproject downwardly and enter locating holes 5ft in the attached leaves 35.

In operation, a flat sheet of metal lath til is arranged in the brake as shown in Fig. l, and the removable leaf` lill' is mounted on one of the iixe'd leaves to clamp` a portion of the' lath therebetween. Although it makes no difference which of the fixed leaves 36 firstv receives the removable leaf de, for the purpose of illustration the latter is shownl onthe leaf 35 disposed at the left of beam 3d. The first operation in forming the lath zo is to swing the panel 38 which is attached to next operation is tol articulate the leaf Sie at the left of beam (i4l to the position shown in t while still holding'the lath clamped solidly be-y tween leaves 36 and ll. This operation forms a relatively wideY section or side 5d in the lath.

The raised leaf V3l; and panel 3-8A are then lowered a relatively narrow side 58 therein, which side is disposed directly above the support 3d and in opposed relation to the two sides or anges 52 .(FigxB 'Ihiscompletes the preforming operation and-the finished lath is disengaged from the :brake merely by removing the leaf lill.

The preformed metal lath is shown in edgewise elevation'in Fig. 9, and it will be observed that it ter coating fnxedl to the'wall.

is generally rectangular in form. The two opposed'sides `Sfffare vvrelatively wide, while the sides formedby overlapping'ianges 52 and side 5S are relatively "ria-rrow.r

To apply the iatn to the wan it is merely necessary to drive nail's'ld or the like" through th'efsidesor flanges-52 and 5s in. the manner .hereinabove describedand as shown in Fig.Y 2. If ordinarymetar maiisarei used to' fasten 'the pre-formed? metal lths" 201 toI the walls, I prefer' to' use, in addition, a number of galvanized 'metal nai-levez.
